Hi AhmedAbdeen & RobinZ1, welcome to the community!

I agree with @Uliwooly - here are some additional instructions on running the actual repair:

1. Install and open PC Companion then select Support Zone.
2. Phone Software Update.
3. Start.
4. Repair Phone
5. Continue
6. Accept data removal
7. Next
8. Wait for prepare
9. Select Phone
10. Follow the connection steps

Running the software repair on Bridge for Mac:
1. Launch Bridge for MAC without the handset connected.
2. On the Main Window select "Xperia > Repair Xperia Device".
3. Ensure the phone is charged and select "Ok" in the following window.
4. Select Continue on the following page.
5. Wait until the initialising step is finished the continue as below.
6 . Select your model of phone from the list that appears

Unfortunately, the problem still exists

* I did Reset phone to factory settings, but the problem remains as it is

* Reinstall the latest update with PCC , but also the problem still exists

The problem is :
cut up sound through regular calls, and the hottest phone when browsing the Internet or when using multiple users

Please help me

The phone will get hot while using,that is normal. But related to calls,have you tried other SIM cards?
